Abstract

Système d'injection de combustible à modulation de fréquence pour moteur à combustion interne à signal analogique proportionnel à une fonction de signaux électriques de pression dans la tubulure d'admission et de vitesse du moteur. Système comprenant un oscillateur sensible au signal analogique et à un signal de référence pour engendrer un signal électrique modulé en fréquence, et un générateur d'impulsions sensible audit signal électrique pour engendrer un signal électrique impulsionnel qui est adressé à un moyen d'injection de combustible pour permettre la fourniture de la quantité demandée de combustible au moteur.
